Pratt & Whitney pleased with PurePower PW1524G engine tests

American company Pratt & Whitney says that it is pleased with initial ground testing on its new engine, which is designed to be more environmentally-friendly because it uses less fuel.

Experts subjected the PurePower PW1524G engine, which will power the Bombardier CSeries aircraft, to almost 200 hours of tests at the companys West Palm Beach facility.

Bob Saia, vice president, Next Generation Product Family, said: ''The engine continues to exceed our expectations. We have already completed an unprecedented amount of testing on this first engine, including a full structural evaluation, performance, noise and emissions testing.''

The PurePower engine uses a gear system that allows the fan to operate at a different speed than the low-pressure compressor and turbine, which helps it produce double-digit improvements in fuel efficiency and environmental emissions as well as a 50 per cent reduction in noise.

The Cseries aicraft being produced by Canadian firm Bombardier is due to enter service in 2013.
